Hi and congrats on your baby! That's exciting!! You are probably close to being able to find out the sex! Anyway, is "live" supposed to be "lube"?
So, it could be a yeast infection. I, for some reason, got those a little easier when pregnant. The ph of the vagina may be a little different or something. Not really sure why but yeast infections when pregnant aren't uncommon. My doctor would give me a pill called Diflucan that you can take and knocks it right out. So, yes. I'd see if you are still itching tomorrow and if so, call your doctor. They swab your discharge and give you the medicine if it is yeast. Pressure to pee. That is more a uti symptom but you have had a uti so you are familiar with that. You'd know if that was happening. But if you see your doctor, you can mention it and see if they want you to do the pee in a cup thing to test for bacteria. They may or may not. So, call your doc tomorrow if you still itch and nip it in the bud! good luck
